Good morning, I'm new to the boat motor repair, just purchased boat with this outboard motor , I have general knowledge of motor repairs and more , changed all fuel filters , changed fuel pump , changed plugs , changed water pump , checked for oil flow ,and flushed fuel lines , changed both thermostats, changed TPS sensor ,Has eFitch fuel injection , in the process of doing a fuse panel swap on the boat not the motor , My problem is it does not idle if I spray gas into throttle body's it runs once I stop the gas it will run for a while or it or shut off, if I advance the TPS senor it runs fine ,just won't start or idle unless I do 1 of the 2 , water for cooling is hooked up at all time while testing , could this a cold start system issue, or a choke issue , not original motor of boat ,Thank you
